UK Data Explorer is an online visualization tool that uses UK Census 2011 data to visualize hundreds of different measures. Following is a series of maps showing the household car ownership in London including no car, 1 car, 3 cars, and 4 cars in the household. Dark blue roughly represents >2.5% of households and light blue to white represents <2.5% of households. Interestingly, as the number of cars in the households increases, the outer suburbs of London becomes darker and inner neighborhoods becomes pretty light or almost white. In other words, households with larger number of cars live in farther suburbs while households in the central areas have fewer cars. This is clearly linked to accessibility to destinations, cost of having a car, and perhaps number of persons in a household.
